Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bread making machine equipped with a plurality of containers for storing bread ingredients.

BACKGROUND OF THE INVENTION In recent years, bread makers have become popular, which automatically bake bread when bread ingredients are placed in a container and the machine starts operating. Moreover, there is a growing demand for a bread maker that can increase the number of containers and bake more bread at one time.

A conventional bread making machine of this type had a configuration as shown in FIG. That is, a storage 2 is provided within the main body 1, and two containers 3a and 3b are arranged within this storage 2.

At the inner bottoms of the containers 3a, 3b, blades sa, sb for kneading the input bread ingredients are rotatably arranged, and the blades 6a.

The rotational force of the motor 8 is transmitted to the belt 6b via the pulleys 6a, 6b and the belt 7. The above blades SA, SB, pulleys EA, SB, belts and motor 8 constitute a kneading means. In addition, the container 3a
, 3b are provided with heaters aa and 4b, and a temperature sensor 9 that detects the humidity of the container 3a is in contact with the side wall of the container 3&. This temperature sensor 9 is connected to temperature detection means 1o, and this temperature detection means 10
The temperature signal of the container 3a is output from the control means 11 to the control means 11. The control means 11 controls the motor drive means 12. based on the temperature signal. The heater driving means 13 is operated to control the motor 8 and heaters 4a and 4b.

Next, control by the control means 11 will be explained.

If the operation is started without stirring, the container 3-
The motor driving means 12 is operated to knead the bread ingredients in the containers 3a and 3b with the blades sa and sb until the temperatures of a and ab reach the fermentation temperature (kneading step). This practice 9
When the process is completed, the heater drive means 13 is operated,
The temperature of the containers 3a and 3b is controlled to the fermentation temperature (fermentation process). When this fermentation process is finished, the container 3a is heated to baking temperature.

The process moves to a firing step in which the temperature of step 3b is increased. In the above-mentioned kneading process, when the bread ingredients are kneaded, they may self-heat and exceed the fermentation temperature.

In order to ensure good fermentation in the next fermentation process, the temperature of the container 3a is detected by the temperature detection means 10 so that the temperature does not rise too much during the kneading process, and when the temperature reaches the fermentation temperature, the fermentation process starts. It is being migrated. Temperature detection means 10 at this time
Although the temperature signal is temperature information only on the container 3a side, the control means 11 assumes that the temperature on the container 3b side is almost equal to the temperature on the container 3a side and controls the heating of the heaters 4a and 4h. .

Once the fermentation process is complete, the container 3 will be heated to the baking temperature.
The process moves to a firing step in which the temperatures of a and 3b are increased.

Problems to be Solved by the Invention However, in the above conventional configuration, the heaters 4a,
4b is controlled only by the temperature signal from the container 3a side, for example, if a large amount of bread ingredients is put into the container 3a side,
When the rated amount of bread ingredients is put into the container 3b side, the container 3
Since the temperature increase on the side a is smaller than the temperature rise on the side of the container 3b, by the time the side of the container 3a reaches the fermentation temperature, the temperature of the side of the container 3b has already exceeded the fermentation temperature, and the fermentation process can proceed directly. The problem was that the fermentation did not work properly, resulting in poor bread quality.

In view of the above-mentioned problems, it is an object of the present invention to prevent extremely poor quality of bread even when different amounts of bread ingredients are put into a plurality of containers.

Means for Solving the Problems In order to solve the problems, the present invention provides temperature sensing means provided corresponding to each container to detect the temperature of a plurality of containers storing bread ingredients; A control means receives a signal from the temperature detection means and controls the heating means and the kneading means to proceed with the bread making process, and the control means controls the bread ingredients for a certain period of time or until the temperature detection means reaches the fermentation temperature. In the kneading process of kneading bread ingredients by the kneading means, the kneading process is controlled to be terminated by any one of the detected temperatures of the temperature detection means that reaches near the upper limit of the fermentation temperature range earliest. That is.

Further, in the present invention, the control means is configured to control the kneading process to end when the average value of the temperatures detected by each temperature detection means reaches the center value of the fermentation temperature range during the kneading process. .

Furthermore, in the present invention, the control means terminates the kneading process in response to a signal that reaches near the lower limit of the fermentation temperature range latest among the detected temperatures of the respective temperature detection means during the kneading process. The configuration is such that the control is performed.

Effect According to the above configuration, the temperature of each of the plurality of containers containing different amounts of bread ingredients is detected by the temperature detection means, and among the detected temperatures, the one whose temperature rises the fastest, that is, the temperature of the container with the least amount of bread ingredients is detected. When the temperature of the product reaches around the upper limit of the fermentation temperature range, the kneading process is terminated.In this case, the temperature of other containers is around the fermentation temperature, so fermentation will be poor and the result of the bread will be extremely poor. It won't happen. Similarly,
When the average value of the temperatures detected by each temperature detection means reaches the center value of the fermentation temperature range, the kneading process is terminated, and the temperature detected by each temperature detection means, the one whose temperature increases most slowly is the fermentation temperature range. When the kneading process is completed when the temperature reaches around the lower limit of , the temperature of the other containers has reached around the fermentation temperature, so the bread will not be extremely poor due to poor fermentation.

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 4.

The structure of the bread maker according to this embodiment is shown in FIG. 1, and the same parts as in the conventional structure are given the same numbers and their explanations will be omitted.

In FIG. 1, IQa, 10b is a container 3a.

This temperature detecting means 10a is a temperature detecting means to which temperature sensors 9a and 9b in contact with the temperature sensor 3b are connected.

The temperature signal 10b is output to the determining means 14 and the comparing means 16. The comparison means 15 is the set value storage means 1.
6 and the temperature detection means 10a, 1.
The temperature signal from 0b is compared with the temperature signal from 0b, and in the case of claim 1 of the present invention, the temperature detection means 10a or 1ob that reaches the vicinity of the fermentation temperature range earliest is determined. Moreover, in the case of claim 3, the temperature detection means 10a or 10b that reaches near the lower limit of the fermentation temperature range latest is determined. Based on this determination result, the determination means 14 switches the temperature signal from the temperature detection means 10a or 1ob and outputs it to the control means 11. In the case of claim 2, the determination means 14 determines whether the average value of the temperature detection means 10a and 10b has reached the center value of the fermentation temperature range, and transmits the temperature signal to the control means 1.
Output to 1. Then, the control hand 811 terminates the kneading process based on the temperature signal from the determination means 14. Further, the control means 11 ends the kneading process when there is no end output from the determination means 14 even after a certain set time set by the set time means 18 has been reached.

The control means 111 determination means 14. Comparison means 16. Setting value storage means 16. The setting time means 18 is composed of a microcomputer 17.

Next, the control flow of the microcomputer 17 will be explained with reference to FIGS. 2 to 4. Figure 2 shows claim 1 of the present invention.
FIG. 3 is a flowchart regarding claim 2, and FIG. 4 is a flowchart regarding claim 3.

First, FIG. 2 will be explained. When the operation is started, in step 21, the motor drive means 12 starts controlling the motor drive in order to knead the bread ingredients. Next step 22
determine whether the temperature of the container 3a has reached the set value,
If the container 3a has reached the destination, the motor drive control is terminated in step 26. On the other hand, if the temperature of the container 3b has not reached the set value, it is determined in step 23 whether the temperature of the container 3b has reached the set value, and if the temperature of the container 3b has reached the set value, step 26
to end the motor drive control. On the other hand, if the time has not been reached, it is determined in step 24 whether a certain set time has elapsed. If the set time has elapsed, the motor drive control is terminated in step 25. On the other hand, if the time has not elapsed, the process returns to step 22. When the motor drive control is stopped in step 26, a fermentation process and a baking process are performed in steps 26 and 27, and the operation is ended.

Next, FIG. 3 will be explained. When the operation starts, the motor drive means 1 is activated in order to knead bread ingredients in step 31.
At step 2, motor drive control is started.

Next, in step 32, the temperature Ta of the container 3a and the temperature Tb of the container vi3b are inputted. T in step 33
Find the average value T0 of a and Tb. Its average value T. It is determined in step 34 whether or not the set value has been reached, and if it has been reached, the motor drive control is terminated in step 36. On the other hand, if the predetermined time has not been reached, it is determined in step 35 whether a certain set time has elapsed, and if the predetermined time has not elapsed, the process returns to step 32. On the other hand, if the time has elapsed, the motor drive control is ended in step 36.

When the motor drive control is finished in step 36, the fermentation process and baking process are performed in steps 37 and 38, and the operation is finished.

Further, FIG. 4 will be explained. When the operation starts, the initial Mffi of set temperature flags A and H is set to rO in step 41.
Make it J. In step 42, the motor drive means 12 starts controlling the motor drive in order to knead the bread ingredients. Next, in step 43, it is determined whether the temperature of the container 3a has reached the set value, and if so, in step 44, the set temperature flag A is set to "1" and the process proceeds to step 46. on the other hand,
If the temperature has not reached the set value, the process directly proceeds to step 45, and in step 46 it is determined whether the temperature of the container 3b has reached the set value. If it has reached the set value, the set temperature flag B is set to "1" in step 46. Then proceed to step 47. On the other hand, if the temperature has not been reached, the process directly proceeds to step 47, where it is determined whether or not the set temperature flags A and B are "1". If A=B=r1, the motor drive control is ended in step 49. On the other hand, A=
If B=r1J does not hold, it is determined in step 48 whether a certain set time has elapsed, and if it has not elapsed, the process returns to step 43. - On the other hand, if it has elapsed, the motor drive control is ended in step 49. When the motor drive control is finished in step 49, the fermentation process and baking process are performed in steps 50 and 51, and the operation is finished.

Next, temperature changes in each container 3a, 3b during the kneading process will be explained with reference to FIG. Curve A in the figure shows the temperature change of the container into which a large amount of bread ingredients has been put, and curve B shows the temperature change of the container into which the rated amount of bread ingredients has been put. When the bread ingredients begin to be kneaded, the temperature begins to rise due to self-heating. Since the container of curve A has more material,
Its temperature rise will be slower than that of the curve B vessel. As an embodiment of claim 1, if the upper limit of the fermentation temperature range is set, the kneading process is shifted to the fermentation process when the curve B reaches the upper limit, and the curve A is the fermentation temperature range. Since the results are closer to each other, the quality of the bread in the two containers can be improved. Further, as an embodiment of claim 2, if the center value of the fermentation temperature range is set as the set value, when the curve C, which is the average value of the curve A and the curve B, reaches the set value 1ifK, the curve A
and curve B approach the fermentation temperature, respectively.
The quality of the bread in the two containers can be improved.

Further, as an embodiment of claim 3, if the lower limit of the fermentation temperature range is set as a set value, when both curve A and curve B exceed the set value, the kneading process is shifted to the fermentation process, thereby changing the curve. Since A and fSB are closer to the fermentation temperature, it is possible to improve the quality of the bread in the two containers.

In addition, although the said Example shows the case where there are two containers, it cannot be overemphasized that this invention can be applied also to the thing equipped with three or more containers.

Effects of the Invention As is clear from the description of the embodiments described above, according to the present invention, in the kneading process, the temperature of the entire container can be moved to the next fermentation process in a state closer to the fermentation temperature. It will no longer be the case that the quality of the bread becomes extremely poor due to defects.
